Biofortification of wheat with zinc for eliminating deficiency in Pakistan: Study protocol for a cluster-randomised, double-blind, controlled effectiveness study (BIZIFED2)

Introduction: Micronutrient deficiencies, commonly referred to as “hidden hunger”, affect more than two billion people worldwide, with zinc and iron deficiency frequently reported. The aim of this study is to examine the impact of consuming zinc biofortified flour (Zincol-2016) on biochemical and functional measures of status in adolescent girls and children living in a low resource setting in Pakistan. Methods and analysis: We are conducting a pragmatic, cluster-randomised, double-blind, controlled trial. A total of 483 households have been recruited from two catchment areas approximately 30-40 km distance from Peshawar. Household inclusion criteria are the presence of both an adolescent girl, aged 10-16 years, and a child aged 2-5 years. The study duration is 12 months, divided into two 6-month phases. During phase 1, all households will be provided with locally procured flour from standard varieties of wheat. During phase 2, clusters will be paired, and randomised to either the control or intervention arm of the study. The intervention arm will be provided with zinc biofortified wheat flour, with a target zinc concentration of 40 mg/kg. The control arm will be provided with locally procured wheat flour from standard varieties with an expected zinc concentration of 20 mg/kg. The primary outcome measure is plasma zinc concentration. Secondary outcomes include anthropometric measurements, biomarkers of iron and zinc status, and the presence and duration of respiratory tract infections and diarrhoea. Ethics and dissemination: Ethical approval was granted from the University of Central Lancashire STEMH Ethics Committee (reference number: STEMH 1014) and Khyber Medical University Ethics Committee (DIR/KMU-EB/BZ/000683). The final study methods will be published in peer reviewed journals, alongside the study outcomes. In addition, findings will be disseminated to the scientific community via conference presentations and abstracts and communicated to the study participants through the village elders at an appropriate community forum. Registration details: The trial has been registered with the ISRCTN registry, study ID ISRCTN17107812

Recognition of and Response to Neonatal Intrapartum-related Complications in Home-birth Settings in Bangladesh

Intrapartum-related complications (previously called \u2018birth asphyxia\u2019) are a significant contributor to deaths of newborns in Bangladesh. This study describes some of the perceived signs, causes, and treatments for this condition as described by new mothers, female relatives, traditional birth attendants, and village doctors in three sites in Bangladesh. Informants were asked to name characteristics of a healthy newborn and a newborn with difficulty in breathing at birth and about the perceived causes, consequences, and treatments for breathing difficulties. Across all three sites \u2018no movement\u2019 and \u2018no cry\u2019 were identified as signs of breathing difficulties while \u2018prolonged labour\u2019 was the most commonly-mentioned cause. Informants described a variety of treatments for difficulty in breathing at birth, including biomedical and, less often, spiritual and traditional practices. This study identified the areas that need to be addressed through behaviour change interventions to improve recognition of and response to intrapartum-related complications in Bangladesh

Recognition of and Response to neonatal intrapartum-related complications in home-birth settings in Bangladesh.

Intrapartum-related complications (previously called 'birth asphyxia') are a significant contributor to deaths of newborns in Bangladesh. This study describes some of the perceived signs, causes, and treatments for this condition as described by new mothers, female relatives, traditional birth attendants, and village doctors in three sites in Bangladesh. Informants were asked to name characteristics of a healthy newborn and a newborn with difficulty in breathing at birth and about the perceived causes, consequences, and treatments for breathing difficulties. Across all three sites 'no movement' and 'no cry' were identified as signs of breathing difficulties while 'prolonged labour' was the most commonly-mentioned cause. Informants described a variety of treatments for difficulty in breathing at birth, including biomedical and, less often, spiritual and traditional practices. This study identified the areas that need to be addressed through behaviour change interventions to improve recognition of and response to intrapartum-related complications in Bangladesh

EURRECA-Estimating Zinc Requirements for Deriving Dietary Reference Values

Zinc was selected as a priority micronutrient for EURRECA, because there is significant heterogeneity in the Dietary Reference Values (DRVs) across Europe. In addition, the prevalence of inadequate zinc intakes was thought to be high among all population groups worldwide, and the public health concern is considerable. In accordance with the EURRECA consortium principles and protocols, a series of literature reviews were undertaken in order to develop best practice guidelines for assessing dietary zinc intake and zinc status. These were incorporated into subsequent literature search strategies and protocols for studies investigating the relationships between zinc intake, status and health, as well as studies relating to the factorial approach (including bioavailability) for setting dietary recommendations. EMBASE (Ovid), Cochrane Library CENTRAL, and MEDLINE (Ovid) databases were searched for studies published up to February 2010 and collated into a series of Endnote databases that are available for the use of future DRV panels. Meta-analyses of data extracted from these publications were performed where possible in order to address specific questions relating to factors affecting dietary recommendations. This review has highlighted the need for more high quality studies to address gaps in current knowledge, in particular the continued search for a reliable biomarker of zinc status and the influence of genetic polymorphisms on individual dietary requirements. In addition, there is a need to further develop models of the effect of dietary inhibitors of zinc absorption and their impact on population dietary zinc requirements.This is the peer-reviewed version of the article: Lowe Nicola M., Dykes Fiona C., Skinner Anna-Louise, Patel Sujata, Warthon-Medina Marisol, Decsi Tamas, Fekete Katalin, Souverein Olga W., Dullemeijer Carla, Cavelaars Adrienne E., Serra-Majem Lluis, Nissensohn Mariela, Bel Silvia, Moreno Luis A., Hermoso Maria, Vollhardt Christiane, Berti Cristiana, Cetin Irene, Gurinović Mirjana A., Novaković Romana, Harvey Linda, Collings Rachel, Hall-Moran Victoria, "EURRECA-Estimating Zinc Requirements for Deriving Dietary Reference Values" 53, no. 10 (2013):1110-1123, [https://doi.org/10.1080/10408398.2012.742863

Impact of foliar herbivory on the development of a root-feeding insect and its parasitoid

The majority of studies exploring interactions between above- and below-ground biota have been focused on the effects of root-associated organisms on foliar herbivorous insects. This study examined the effects of foliar herbivory by Pieris brassicae L. (Lepidoptera: Pieridae) on the performance of the root herbivore Delia radicum L. (Diptera: Anthomyiidae) and its parasitoid Trybliographa rapae (Westwood) (Hymenoptera: Figitidae), mediated through a shared host plant Brassica nigra L. (Brassicaceae). In the presence of foliar herbivory, the survival of D. radicum and T. rapae decreased significantly by more than 50%. In addition, newly emerged adults of both root herbivores and parasitoids were significantly smaller on plants that had been exposed to foliar herbivory than on control plants. To determine what factor(s) may have accounted for the observed results, we examined the effects of foliar herbivory on root quantity and quality. No significant differences in root biomass were found between plants with and without shoot herbivore damage. Moreover, concentrations of nitrogen in root tissues were also unaffected by shoot damage by P. brassicae larvae. However, higher levels of indole glucosinolates were measured in roots of plants exposed to foliar herbivory, suggesting that the development of the root herbivore and its parasitoid may be, at least partly, negatively affected by increased levels of these allelochemicals in root tissues. Our results show that foliar herbivores can affect the development not only of root-feeding insects but also their natural enemies. We argue that such indirect interactions between above- and below-ground biota may play an important role in the structuring and functioning of communities

Array CGH Phylogeny: How accurate are Comparative Genomic Hybridization-based trees?

<p>Abstract</p> <p>Background</p> <p>Array-based Comparative Genomic Hybridization (CGH) data have been used to infer phylogenetic relationships. However, the reliability of array CGH analysis to determine evolutionary relationships has not been well established. In most CGH work, all species and strains are compared to a single reference species, whose genome was used to design the array. In the accompanying work, we critically evaluated CGH-based phylogeny using simulated competitive hybridization data. This work showed that a limited number of conditions, principally the tree topology and placement of the reference taxon in the tree, had a strong effect on the ability to recover the correct tree topology. Here, we add to our simulation study by testing the use of CGH as a phylogenetic tool with experimental CGH data from competitive hybridizations between <it>N. crassa </it>and other <it>Neurospora </it>species. In the discussion, we add to our empirical study of <it>Neurospora </it>by reanalyzing of data from a previous CGH phylogenetic analysis of the yeast <it>sensu stricto </it>complex.</p> <p>Results</p> <p>Array ratio data for <it>Neurospora </it>and related species were normalized with loess, robust spline, and linear ratio based methods, and then used to construct Neighbor-Joining and parsimony trees. These trees were compared to published phylogenetic analyses for <it>Neurospora </it>based on multilocus sequence analysis (MLSA). For the <it>Neurospora </it>dataset, the best combination of methods resulted in recovery of the MLSA tree topology less than half the time. Our reanalysis of a yeast dataset found that trees identical to established phylogeny were recovered only by pruning taxa - including the reference taxon - from the analysis.</p> <p>Conclusion</p> <p>Our results indicate that CGH data can be problematic for phylogenetic analysis. Success fluctuates based on the methods utilized to construct the tree and the taxa included. Selective pruning of the taxa improves the results - an impractical approach for normal phylogenetic analysis. From the more successful methods we make suggestions on the normalization and post-normalization methods that work best in estimating genetic distance between taxa.</p

Root Herbivore Effects on Aboveground Multitrophic Interactions: Patterns, Processes and Mechanisms

In terrestrial food webs, the study of multitrophic interactions traditionally has focused on organisms that share a common domain, mainly above ground. In the last two decades, it has become clear that to further understand multitrophic interactions, the barrier between the belowground and aboveground domains has to be crossed. Belowground organisms that are intimately associated with the roots of terrestrial plants can influence the levels of primary and secondary chemistry and biomass of aboveground plant parts. These changes, in turn, influence the growth, development, and survival of aboveground insect herbivores. The discovery that soil organisms, which are usually out of sight and out of mind, can affect plant-herbivore interactions aboveground raised the question if and how higher trophic level organisms, such as carnivores, could be influenced. At present, the study of above-belowground interactions is evolving from interactions between organisms directly associated with the plant roots and shoots (e.g., root feeders - plant - foliar herbivores) to interactions involving members of higher trophic levels (e.g., parasitoids), as well as non-herbivorous organisms (e.g., decomposers, symbiotic plant mutualists, and pollinators). This multitrophic approach linking above- and belowground food webs aims at addressing interactions between plants, herbivores, and carnivores in a more realistic community setting. The ultimate goal is to understand the ecology and evolution of species in communities and, ultimately how community interactions contribute to the functioning of terrestrial ecosystems. Here, we summarize studies on the effects of root feeders on aboveground insect herbivores and parasitoids and discuss if there are common trends. We discuss the mechanisms that have been reported to mediate these effects, from changes in concentrations of plant nutritional quality and secondary chemistry to defense signaling. Finally, we discuss how the traditional framework of fixed paired combinations of root- and shoot-related organisms feeding on a common plant can be transformed into a more dynamic and realistic framework that incorporates community variation in species, densities, space and time, in order to gain further insight in this exciting and rapidly developing field

Pharmacological Fingerprints of Contextual Uncertainty

Successful interaction with the environment requires flexible updating of our beliefs about the world. By estimating the likelihood of future events, it is possible to prepare appropriate actions in advance and execute fast, accurate motor responses. According to theoretical proposals, agents track the variability arising from changing environments by computing various forms of uncertainty. Several neuromodulators have been linked to uncertainty signalling, but comprehensive empirical characterisation of their relative contributions to perceptual belief updating, and to the selection of motor responses, is lacking. Here we assess the roles of noradrenaline, acetylcholine, and dopamine within a single, unified computational framework of uncertainty. Using pharmacological interventions in a sample of 128 healthy human volunteers and a hierarchical Bayesian learning model, we characterise the influences of noradrenergic, cholinergic, and dopaminergic receptor antagonism on individual computations of uncertainty during a probabilistic serial reaction time task. We propose that noradrenaline influences learning of uncertain events arising from unexpected changes in the environment. In contrast, acetylcholine balances attribution of uncertainty to chance fluctuations within an environmental context, defined by a stable set of probabilistic associations, or to gross environmental violations following a contextual switch. Dopamine supports the use of uncertainty representations to engender fast, adaptive responses. \ua9 2016 Marshall et al
